What is the difference between planetary reducer and gear reducer?
Planetary gear reducer and gear reducer are two kinds of common deceleration equipment. They have different structures and different technical parameters, and the transmission efficiency, deceleration range and application scenarios are also different.
Planetary reducer has small structure, small well spacing, high accuracy, long service life and large rated output torque. However, the price is a little expensive. Planetary reducer is generally used when high torque is required in limited space, that is, small volume and large torque. Its reliability and service life are better than spur gear reducer.
Spur gear reducers are used for low current consumption, low noise, high efficiency and low cost applications. Planetary reducer has small volume, large output torque and high transmission efficiency. Where there are the above requirements, planetary reducer can be used in many industries such as cutting machine, pipe bender, bucket wheel, cement production line, oil processing, chemical fertilizer, power station, cement, glass and so on.
The comparison is as follows:
1、 Structure comparison:
The main transmission structure of planetary reducer is composed of planetary gear, sun gear, inner ring, transmission shaft, box, motor and output shaft, which can realize the separate effect of dynamic classification and multi tooth meshing. It has high stiffness, high precision (within 1 point for the first stage) and high transmission efficiency (97% – 98% for the short stage), which is unmatched by ordinary gear reducer.
The main transmission structure of gear reducer is composed of box, gear, shaft, bearing and bearing cover. The three-stage gear reducer is composed of multiple groups of gears. Features of planetary reducer: light weight, small volume, large transmission ratio range, high efficiency, stable operation, low noise, strong adaptability, high transmission accuracy and wide deceleration range. It is a precision reducer with a reduction ratio of 0.1-0.5 R / min.
2、 Gear reducer features:
1. The gear is made of high-strength low-carbon alloy steel and carburized and quenched. The hardness of the tooth surface reaches HRC58-62. The gears adopt NC Polishing Process with high precision and good contact.
2. High transmission rate: single stage is greater than 96.5%, second stage is greater than 93%, and third stage is greater than 90%.
3. Stable operation and low noise.
4. Small size, light weight, long service life and high bearing capacity.
3、 Application:
gear reducer: suitable for metallurgy, mining, hoisting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmaceutical, etc.
planetary reducer: small volume, light weight, high loading capacity, long service life, stable operation and low noise. It has the inherent characteristics of power split and multi tooth meshing. WGN fixed shaft transmission reducer, WN sub parent gear transmission reducer and elastic load small tooth difference reducer are new planetary Series in industrial departments such as hoisting and transportation, engineering machinery, metallurgy, mining, petrochemical, engineering machinery, light industrial fiber, medical instruments, instruments, automobiles, ships, weapons and aerospace.
